There is a particularly bitter irony in Erin Patterson’s latest legal dilemma: the Australian woman who went to court hoping to overturn her triple-murder convictions has emerged with a punishment considerably harsher than the one she was originally given. Her attempt to secure another chance at freedom has instead ended with the prospect of spending the remainder of her life behind bars, without the possibility of parole.
On October 30, 2026, Victoria’s Court of Appeal dismissed Patterson’s challenge to her convictions while simultaneously granting prosecutors’ appeal against the leniency of her original sentence. The three-judge panel concluded that the 33-year non-parole period imposed in September 2025 was inadequate given the extraordinary planning, deception, and cruelty involved in her crimes.
Justice Stephen McLeish, delivering the court’s decision alongside Justices Lesley Taylor and Peter Kidd, described Patterson’s offending as “extraordinarily cold and calculated.” The judges concluded that the circumstances involved such “shocking criminality” that establishing a minimum period before parole could be considered was inappropriate.
It was an extraordinary reversal of fortune for the 52-year-old mother of two. Having initially received three life sentences for murder and another 25 years for attempted murder, Patterson had faced the possibility of parole in 2056, when she would have been approximately 82. That possibility has now disappeared.
Seven Grounds of Appeal, but No Escape From Conviction

Patterson’s legal team had presented seven grounds of appeal as they sought to convince the court that her trial was compromised and that her convictions should be overturned.
One particularly significant argument concerned the arrangements for jury accommodation during the high-profile proceedings in Morwell, Victoria. Jurors had stayed at the same hotel as members of the prosecution team and witnesses, including the lead homicide detective.
Her barrister, Richard Edney, described the accommodation situation as “catastrophic” to the defense, arguing that the possibility of inappropriate contact between jurors and prosecution witnesses could not be excluded.
However, the appeals court found no evidence establishing that such interactions had occurred. The judges concluded there was “no objective basis for a fair-minded person to reasonably apprehend that the jury might not have discharged its function of rendering a verdict according to law.”
The court also rejected challenges to the admission of important circumstantial evidence, including cellphone data placing Patterson near locations where death cap mushrooms had been reported to a citizen-science website.
Although Patterson’s lawyers secured permission to pursue two of their seven appeal grounds, neither succeeded. The convictions therefore remained intact, with the court not merely deciding whether procedural shortcomings justified another trial, but also whether the original punishment adequately reflected the seriousness of the crimes.
